Fast Channel Zapping with Destination-Oriented Multicast for IP Video Delivery

Xiaohua Tian, Yu Cheng, Xuemin Shen
2013 IEEE Transactions on Parallel and Distributed Systems  
Channel zapping time is a critical quality of experience (QoE) metric for IP-based video delivery systems such as IPTV.  ...  With a solution proposed to resolve the start-up effect, we rigorously prove that a zapping delay bound equal to the subchannel time shift is guaranteed by the updated TSS-based model.  ...  The time it takes for the new TV program to start playing from the time a request to change to that channel happens is zapping time, which is a critical quality of experience (QoE) metric for IPTV systems  ...
